You might have to give your Audi a blowjob. A few years ago I could not open my trunk lid (86 4kcsq). I pulled out the seat bottom, spotted the pressure line that seemed like it was going back towards the trunk - L/Rear side as I recall - disconnected it, applied positive air pressure that Monica Lewinsky would be proud of, and, voila! Trunk opens! No s*#t! Good Luck! Craig Lebakken
